TFE and Spt4/5 open and close the RNA polymerase clamp during the transcription cycle [PDF]

, 2016
Transcription is an intrinsically dynamic process and requires the coordinated interplay of RNA polymerases (RNAPs) with nucleic acids and transcription factors.

Poly(A) Polymerase and Poly(G) Polymerase in Wheat Chloroplasts [PDF]

Proceedings of the National Academy of Sciences, 1974
Extracts of wheat chloroplasts contain a poly(A) polymerase which can polymerize AMP residues from ATP onto an RNA primer. Whole extracts of wheat leaves also contain another poly(A) polymerase which is present in much larger amount and is probably derived from the nuclei.

Chicken eEF1α is a Critical Factor for the Polymerase Complex Activity of Very Virulent Infectious Bursal Disease Virus

Viruses, 2020
Infectious bursal disease (IBD) is an immunosuppressive, highly contagious, and lethal disease of young chickens caused by IBD virus (IBDV). It results in huge economic loss to the poultry industry worldwide.

The RNA Polymerase II Core Promoter in Drosophila. [PDF]

, 2019
Transcription by RNA polymerase II initiates at the core promoter, which is sometimes referred to as the "gateway to transcription." Here, we describe the properties of the RNA polymerase II core promoter in Drosophila The core promoter is at a strategic

The Methyltransferase Region of Vesicular Stomatitis Virus L Polymerase Is a Target Site for Functional Intramolecular Insertion

Viruses, 2019
The L-protein of vesicular stomatitis virus (VSV) is a single-chain multi-domain RNA-dependent RNA polymerase. Previously reported attempts of intramolecular insertions of fluorescent proteins into the L-protein resulted in temperature-sensitive and ...

A splicing-dependent transcriptional checkpoint associated with prespliceosome formation [PDF]

, 2014
There is good evidence for functional interactions between splicing and transcription in eukaryotes, but how and why these processes are coupled remain unknown.

DNA Polymerase ε: A Polymerase of Unusual Size (and Complexity) [PDF]

, 2008
Publisher Summary DNA polymerase epsilon (Pol epsilon) is a large, multi-subunit polymerase that is conserved throughout all eukaryotes. In addition to its role as one of the three DNA polymerases responsible for bulk chromosomal replication, Pol epsilon is implicated in a wide variety of important cellular processes, including the repair of damaged ...

Poliovirus-specific primer-dependent RNA polymerase able to copy poly(A) [PDF]

, 1977
A template-dependent RNA polymerase has been isolated from poliovirus-infected cells by assaying for the ability of the enzyme to copy poly(A) complexed to an oligo(U) primer.

Confidence intervals for nonhomogeneous branching processes and polymerase chain reactions

, 2005
We extend in two directions our previous results about the sampling and the empirical measures of immortal branching Markov processes. Direct applications to molecular biology are rigorous estimates of the mutation rates of polymerase chain reactions ...
